Reality TV star Kelly Osbourne wishes her colleagues would stop treating her like a teenager.

The 28-year-old star is a co-host on hit TV show 'Fashion Police' and thinks those around her should show her a bit more "respect".

Osbourne took to Twitter today (April 4) to write: ''I know I look young but some of the people I work with have got to stop treating me like Im 15 I already have a Mum & deserve more respect! (sic)''

Despite her negative comments, the star reiterated that she loves working with her team, which includes Joan Rivers, Giuliana Rancic and George Kotsiopoulos.

Osbourne added: ''All bitching aside I do love everyone I work with! I guess thats why its bugs me so much! (sic)''

Last month Osbourne suffered a seizure while filming an episode of her E! show, but has since returned to work.

The singer-and-television-personality was rushed to hospital in Los Angeles after falling out of her chair and convulsing on set, but was given the all-clear soon afterwards.

She took to Twitter to announce her return to health at the end of last month: "#SoHappy I just got the al clear from my doctor to go back to work tomorrow!!!!! (sic)."
